Outside light issue

[bgatty68]

Hi guys my twin outside lights have stopped working now I understand the basics on electrical work and feel completely competent doing some work, I have a multimeter and just thought I would ask the experts the best route to take. Now the lights have been installed quite a few years ago and I installed them from the ceiling rose in the hallway and that light still works and all downstairs lights are ok and nothing has tripped out on the consumer box and I thought it was the bulbs at first -4 of them- but I put a spare bulb I had in but still nothing? Any ideas are welcome

Picture of said light?

Also have you opened said light? water ingress

Will look for water ingress now

Are they connected off a fused spur?

They should be to prevent any external fault causing a loss of internal lights (in this case).

Never heard anyone doing that before.

17th edition from my understanding requires a safe means of isolation for maintenance and in the event of a fault.

Why take a risk by taking a feed direct from lighting circuit or back of socket circuits. Outside fault has potential to create a fault rendering rcd unresettable until fault has cleared. If that happens when it's dark you're left in a tricky spot to rectify the fault. A simple fcu would eradicate the problem immediately.

I understand the reasoning, but I have never heard of anyone doing it. (Obviously if its fed from a ring then yes)

I always do it as good practice. Doesn't take that much longer and extra material cost is small.

I think that is the most likely scenario, fused spur or switched fused... Unusual for both to go pop otherwise (without anything internal going pop)

What's the difference between a switched fuse and a fused spur? I thought they were the same?

One has a switch, the other doesn't.

Ah, ok, thanks. Obvious really . I didn't even notice there were unswitched fused spurs...

Hey guys I appreciate the debate but I’ve chrcked and there’s no water ingress. Just needed some advice on testing the lights with multimeter ? Checking for voltage etc

[Someone-Else]

I am concerned that if you have to ask that, should you be doing this? Electricity has no prejudices, it kills anyone.

BUT what you could do is take the light fitting down and check its resistance.

Switch the mains to the light is off first.

Ok guys wanted to give an update.
I checked out the light switch and this is ok and the cables going to the lights and there is voltage going to the actual lights but obviously nothing works and there is no water ingress.
So my next question is what would be the next step on why the lights are not working as there is two lights and power to them ? Any other ideas would be welcome (Ive changed the bulbs)
